What is expected?

Not to error out

What is actually happening?

Error from vue core

Oh, umm I just filed this same bug under vue-router: https://github.com/vuejs/vue-router-next/issues/778

You sure this is a core bug and not a bug with the implementation of router-view?

Seems like it - I'll close my dupe. Sorry for the noise!
